Description

Technical Field

[0001] The invention relates to the technical field of antifreeze devices, and in particular to a tap water antifreeze pressure relief device. Background Art

[0002] At present, water is the source of human life. People's lives are closely related to water. The health of drinking water directly affects the health of the human body. At first, people relied on digging wells or directly taking water from rivers and lakes for drinking. However, with the pollution of the environment, most of the river water and well water cannot be directly drunk. Later, humans used filtered tap water to supply people with drinking water, and the most common tap water intake terminal is a faucet. Now in many places in the north, the outer periphery of the water pipes will be covered with an insulation layer and a heating layer to ensure that the water pipes will not be frozen or cracked, but the connection section between the water pipe and the faucet cannot be well insulated. Moreover, in the prior art, many existing faucets do not have an antifreeze function. In the northern region, when taking water in the morning, it is often found that the water in the faucet has frozen and the tap water cannot be released. It is often necessary to use hot water to scald the faucet, and the volume of the water expands after freezing, which can easily break the water pipe, causing inconvenience in water use. Summary of the invention

The bottom of the lower shell is fixedly connected to the insulation pipe, the insulation pipe is communicated with the lower shell, the water pipe is accommodated in the insulation pipe, the inner liner is accommodated in the lower shell, one end of the conduit is fixedly connected to the water pipe, the other end of the conduit is fixedly connected to the inner liner, the conduit communicates the water pipe and the inner liner, there is a gap between the inner liner and the inner wall of the lower shell, the upper shell is fixedly connected to the lower shell, and the breathing valve is installed on the top of the upper shell.

[0006] Furthermore, a through hole is provided at the connection between the lower shell and the insulation pipe, and the conduit connects the inner tank and the water pipe together at the through hole.

[0011] Beneficial effects of the present invention:

[0012] 1.

[0018] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0019] Please refer to Figure 1-4The present invention proposes a tap water antifreeze pressure relief device, which includes an insulation kettle body 10, a breathing valve 16, an inner tank 17, a conduit 18, and a water pipe 19. The insulation kettle body 10 includes an insulation pipe 11, an upper shell 13, and a lower shell 12. The bottom of the lower shell 12 is fixedly connected to the insulation pipe 11, the insulation pipe 11 is communicated with the lower shell 12, the water pipe 19 is accommodated in the insulation pipe 11, the inner tank 17 is accommodated in the lower shell 12, one end of the conduit 18 is fixedly connected to the water pipe 19, and the other end of the conduit 18 is fixedly connected to the inner tank 17. The conduit 18 communicates the water pipe 19 with the inner tank 17. There is a gap between the inner tank 17 and the inner wall of the lower shell 12. The upper shell 13 is fixedly connected to the lower shell 12, and the breathing valve 16 is installed on the top of the upper shell 13. A through hole 14 is provided at the connection between the lower shell 12 and the insulation pipe 11, and the conduit 18 connects the inner tank 17 and the water pipe 19 at the through hole 14. A mounting hole 15 is provided at the top of the upper shell 13, and the breathing valve 16 passes through the mounting hole 15 so that the breathing valve 16 can be installed on the upper shell 13. The tap water antifreeze pressure relief device also includes a first heating wire 20 and a second heating wire 21, the first heating wire 20 is wound and fixed on the periphery of the water pipe 19, and the second heating wire 21 is wound and fixed on the periphery of the inner tank 17. The upper shell 13 and the lower shell 12 are made of transparent materials. The periphery of the inner tank 17 is coated with a layer of light-absorbing material, and the light-absorbing material layer can be selected from a variety of options.

[0020] In this embodiment, the breathing valve 16 is a one-way breathing valve 16. One end of the water pipe 19 is connected to the water pipe 19, and the other end is connected to the faucet. There is a certain gap between the inner liner 17 and the lower shell 12, and the inner wall of the inner liner 17 and the lower shell 12 are not in contact, so that an air layer can be formed between the inner liner 17 and the lower shell 12, which can play a good role in heat preservation. The upper shell 13 and the lower shell 12 are set to be transparent, so that the inner liner 17 can absorb light better, thereby heating the inner liner 17. The first heating wire 20 and the second heating wire 21 can assist in heating and heat preservation of the water pipe 19 and the inner liner 17. The first heating wire 20 and the second heating wire 21 are connected to a solar power supply device. At present, solar constant temperature antifreeze devices are rarely used in extremely cold areas, and it is even rarer to install solar devices on the antifreeze devices of faucets. Therefore, in the tap water antifreeze and pressure relief device of the present invention, the heating wire is connected to the solar power generation device, and then the inner tank can also absorb the heat of the solar energy through the light-absorbing layer to heat and insulate the water in the inner tank. The transparent outer shell allows sunlight to be transmitted to the inner tank, the solar power generation device heats the two heating wires, and the inner tank absorbs solar energy for heating. The dual solar heating and heat preservation functions can achieve a good antifreeze effect.

[0021] In this embodiment, the working process of the tap water antifreeze pressure relief device is: close the faucet before draining the water. When the water comes, the water flows from the pipeline into the water pipe 19. When the water flows into the water pipe 19, the air in the pipeline enters the top of the inner tank 17 from the conduit 18, and then the breathing valve 16 on the top of the upper shell 13 is lifted up. The rubber pad on the breathing valve 16 presses and seals the mounting hole 15, and the entire thermal insulation pot body 10 is in a state of being disconnected from the outside world. The water level in the inner tank 17 drops, and due to the water pressure and the action of the breathing valve 16, the air cannot overflow. When the water is not drained, the water level in the inner tank 17 rises or falls, and pulsations are formed so that the water in the conduit 19 cannot be still, making it difficult to freeze. When the water supply is cut off, the air in the heat preservation kettle body 10 presses the water in the inner tank 17 back into the water pipe 19. At this time, the air pressure in the heat preservation kettle body 10 returns to normal, the breathing valve 16 opens, and then all the water in the inner tank 17 flows back into the water pipe 19. In the case of water supply or water supply cutoff, after the faucet is turned off, due to the presence of the tap water antifreeze pressure relief device, the section of the pipe connecting the water pipe 19 and the faucet is in an empty and waterless state, so the faucet equipped with the device can have an antifreeze effect outdoors.

[0022] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
